“X vs. Y” — the difference and which to pick
- Performance Max vs. Demand GenPMax optimizes for conversion against existing demand; Demand Gen builds new demand in visual surfaces, with creative control.
- Performance Max vs. AI MaxAI Max is an AI layer over Search, with search-term reporting; PMax is a separate, multi-channel campaign with limited placement visibility.
- Target CPA vs. Target ROAStCPA optimizes cost per conversion; tROAS optimizes value returned per unit spent — and requires real conversion values.
- Maximize Conversions vs. Maximize Conversion ValueConversion count vs. conversion value. The choice hinges on one thing: are you passing real conversion values or not?
- AI Overviews vs. AI ModeOverviews lives in the classic SERP and answers the given query; AI Mode is its own surface and manufactures its own sub-questions.
- RAG vs. fine-tuningRAG changes what the model KNOWS at question time; fine-tuning changes HOW it behaves. Facts → RAG. Behaviour → fine-tuning.
- First-party vs. third-party cookiesWho sets the cookie: the domain the user is on (first-party, works) or a third domain (third-party, widely blocked).
- CAPI vs. Enhanced ConversionsCAPI = how the event reaches the platform (server-to-server). Enhanced Conversions = what identifying data the event carries.
- SEO vs. GEOThe mechanism: document ranking (SEO) vs. synthesis from multiple sources, with citation (GEO). SEO becomes the infrastructure for GEO.
